The XtParseAcceleratorTable function compiles
the accelerator table into the opaque internal representation.

The XtInstallAccelerators
function installs the accelerators from source onto destination by augmenting
the destination translations with the source accelerators. If the source
display_accelerator method is non-NULL, XtInstallAccelerators calls it
with the source widget and a string representation of the accelerator
table, which indicates that its accelerators have been installed and that
it should display them appropriately. The string representation of the accelerator
table is its canonical translation table representation.

The XtInstallAllAccelerators
function recursively descends the widget tree rooted at source and installs
the accelerators of each widget encountered onto destination. A common use
os to call XtInstallAllAccelerators and pass the application main window
as the source.
